Twin studies are often used in psychology to determine the relative contributions of genetic and environmental factors to different characteristics, including intelligence, personality, and behavior. By comparing the similarities and differences between identical twins (who share 100% of their genes) and fraternal twins (who share roughly 50% of their genes), researchers can estimate the extent to which genetic and environmental factors contribute to different traits. This method has been used to study a wide range of characteristics, including intelligence, personality disorders, addiction, and more.
